TOWIE star Gemma Collins collapsed in a bathroom this morning after suffering extreme stomach pains - just hours after a night out with her love interest James 'Arg' Argent.

The GC was discovered by her make-up artist on the tiled floor of her bathroom around 9am and rapid medical attention was called for her.

It's feared Gemma could be suffering from kidney stones.

A source told The Sun: "Gemma had filming commitments this morning but everything has ground to a halt following her shock collapse.

"She was getting ready for the day at her makeup artist Lisa's home and then nipped to the bathroom.

"The next thing Lisa knew was that Gemma had fallen to the floor – so she called for immediate medical attention and may now need to go to hospital."

It's thought her filming will be suspended for the time being - meaning she could miss out on the end-of-series Christmas party celebrations.

Just hours before her dramatic collapse, Gemma was out partying with Arg at a pub and posted footage of their night out on her Instagram.

She could be overheard in the video asking someone for an Amaretto in between joining Arg in singing Let's Stay Together.

"I just [heart] it when you sing we have had the best time celebrating your birthday I'm actually so sad to go home. singing means your happy #letsstaytogether I'm so so so proud of you @real_arg I love to see you sing I will watch this so many times lol over and over ha ha," she captioned the video, which was posted in the early hours of the morning.

Earlier in the evening she'd been busy filming scenes for the TOWIE Christmas party episode in Sutton, south west London.

She was spotted walking outside what looked like an upscale hotel deep in conversation while wearing a black winter coat, a fascinator and strappy silver heels.

Mirror Online has contacted TOWIE and Gemma's rep for comment.

What are kidney stones?

Kidney stones are formed of calcium, magnesium and ammonia and grow in the kidneys. Some are small and pass out of the body undetected, while others can grow the size of a golf ball.

The symptoms of kidney stones include nausea, needing to wee more often (and seeing blood when you wee, or feeling pain when you go to the loo), a lower back ache and intense pain in the back or side of the stomach.

People with kidney stones may also feel restless and find it hard to lie still.

Symptoms usually develop when the stone has got stuck in the kidney, starts to travel down the ureter or causes an infection.

They can lead to a kidney infection if one blocks the ureter, the symptoms of which are passing cloudy and bad-smelling urine, feeling very weak, having a high temperature (of 38C or higher) and having chills or shivering.
